This is related to issue #2844 that I raised, more details is provided there.

In summary, using concatenate_runs = True results in an error as regressor names are missing for session dummy variables, this one-line corrects it by adding a session regressor name to the regressor_names variable..

If my interpretation is correct, its an easy fix with a single line I think:
infoout.regressor_names.extend(['run' + str(i + 1)])

This looks sensible. I think it could be written slightly more cleanly. And can you verify that this produces the results you expect?

And do you want to add yourself to the .zenodo.json file?

Suggested change

	infoout.regressor_names.extend(['run' + str(i + 1)])
	infoout.regressor_names.append('run%d' % (i + 1))

Yes, this produces the results I expect, I already use it in my local code.

I will add myself to the zenodo file, thanks!

Just noticed the failing tests. Looks like infoout.regressor_names doesn't exist to extend. If you look at lines 563-564, you need to create the list first. I'm a little curious why it works for you, then...

I'll try to have a deeper look tomorrow.

Also, can you go ahead and merge/cherry-pick 4158583 into this PR instead of having a separate one?

Failing tests

Ok, silly mistake, regressors is an optional argument and so is regressor_names then. In my case I had nuisance regressors and their names so it never complained. Tests for sure have cases without any nuisance covariate. should be Ok by just adding creating the list few lines above.

@hstojic and @effigies - since this creates a without a broken test, it would be great to have a broken test as well. i just asked @hstojic to add that in the original issue.

@satra and @effigies I have been a bit tight on time these few days to add a test and resolve the issue before the new release, it will have to wait for the new one, I'll try to do it soonish

No worries. When you get some time.

Hi @hstojic. Just a bump to let you know we'll be aiming to have everything in for the 1.1.9 release by next Friday, Feb 22. Let us know if you need any help on this.
